OIL-CUP.

Specification of Letters Patent.

Patented Feb. 11,1908.

I Application filed April 20 1907. Serial No. 369.233,

Be it known that I, JosEPH W. KYLE, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Oil-Cups and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to im rovemen'ts in oil cups of the class set forti in the prior application of John B. Reimund and mysel filed May 7, 1906, Serial No. 315,682.

Heretofore oil cups of this class have been somewhat uncertain in feeding the oil. and have often proven unsatisfactory inasmuch as the cups, though feeding the desired amount when full, or nearly full, sometimes feed more slowly as the quantity of oil in the cup decreases, thereby providing insufficient lubrication. Such cups frequently will not feed all of the oil to the journal to be lubri cated, for when the cups are only partly filled the oil instead of assing into the feed tube is deflected past t e same or into the bottom of the cup and an insufficient amount passes into the tube. Furthermore oil cups that are removable from afixed nipple which covers and closes an air displacement aperture, whenan imperfect fit or when the attaching means are slightly worn, ermit centrifugal force to throw the cup s ightly away from the nipple thus admitting sulficient air into the oil cup to cause an im perfect feed of the oil.

- It is an object of this invention to provide connecting means for the cup and, nipple which yieldingly but positively and detachably secure the same in proper relation without the necessity of accurate machining and which insures a perfect fit, independently of the wear of the parts, or any possible working conditions.

It is a further object of this invention to provide means for feeding the oil to the journal at a uniform rate, independently of the amount in the cup and until the cup is empty.

It is also an object of this invention to my invention.

provide an efficient, positively operating device of few parts and which can be quickly and easily detached, filled and replaced and from which the oil will not spill.

The invention consists in the matters hereinafter described and more fully pointed out and defined in the appendedclaims.

On the drawings: Figure 1 is a side elevation of a loose pulley provided with devices embodying my invention. Fig. 2 is an enlarged side elevation of a device embodying Fig. '3 is a section taken on line 3-3 of Fig. 2. Fig. 4 is an enlarged side elevation of the nipple. Fig. 5 is a top plan view of the connecting means. Fig. 6 is an enlarged transverse section of the deflector.

In the drawings: A indicates an oil cup of any desired shape but which is shown as oylindrical and is provided with an integral conical top. A bottom plate a, provided with a peripheral upturned flange 0/, fits Within the cup and is brazed, or otherwise secured in the cup. A central circular aperture surrounded by an upturned flange is provided in said bottom, through which extends the feed pipe or tube B, which is secured therein, in any referred manner to afforda tight joint. aid tube extends into the cup to near the top and outwardly beyond the bottom any desired distance. I

Centrally secured at its base to the top of said cup A is a deflector C, which as shown, is pyramidal in form having four concave sides, and the apex of which is directed axially into the upper end of said tube, to any desired distance.

A nipple D having an externally screw threaded lower end (1 for engagement to the hub of the loose pulley or other revolving element in the journal to be lubricated, is axially bored for its entire length and the outer end of said bore is enlarged to receive the outwardly extending end of the feed tube B therein. The outer end of said nipple is flattened to fit closely against the bottom a, and to seal the vent apertures a therein, when the cup is secured in place. The attaching means comprises a ring E which is brazed, threaded, shrunk or otherwise rigidly secured to the nipple D, and is provided on opposite sides thereof with resilient spring arms ee, adapted to engage in the oppositely disposed slots: 6 similar to bayonet joint notches, in the sides of the cup below the bottom plate a. A slight swell or shoulder a is provided in each notch over which the resilient arms ee are sprung when the cup is engaged on the nipple.

The operation is as follows: The cup is filled through the tube B, and the vent aperture or apertures a allows the air in the cup to escape as the cup fills. The cup and nipple are quickly attached by inserting the resilient arms in said slots 6 and slightly turning the cup, the resilient arms spring over the shoulders and lock the cup from removal except when considerable force is applied. When secured together the nipple closes the vent aperture (1 and prevents the loss of the lubricant therethrough and prevents ingress of air. Furthermore owing to the resilient arms ee, a pressure is always exerted on the cup oppositely to centrifugal force, to hold the bottom a tightly against the top of the nipple, thereby at all times closing the vent aperture. Owing to the deflector C, a part of the oil thrown outwardly by centrifugal force instead passing the top of the tube B, is intercepted by said concave deflector and during each revolution, as the cup assumes an upright position a small portion of the oil is delivered from said deflector to the feed tube and thence through the nipple to the journal. Obviously if desired more than two resilient locking arms may be provided and the deflector may be of any preferred kind or form and the sides of the deflector may be differently shaped. I therefore do not purpose limiting this application other- .wise than necessitated by the prior art.

3. A centrifugally acting oil cup having apermanent bottom therein, a tube extending therethrough, means adapted to deflect the oil into said tube, detachable means engaging said cup to the object to be lubricated and resilient connections between the same and oil cup.

4:. In a device of the class described the combination with an oil cup of a closed bottom therein having a vent aperture therethrough, a feed tube extending through said bottom, a deflector engaged in the top of the cup and extending into said feed tube, a nipple cored to receive the outer end of said tube and adapted to abut against said bottom to close the air vent and resilient means acting against centrifugal force and adapted todetachably secure said cup on said nipple. Y 5. An oil cup wholly closed except for a vent aperture in its bottom for the displacement of air in filling and a filling and feed tube connected through thebottom, a deflector in said cup, a nipple bored to conduct the oil-from said tube to the journal and adapted to engage the cup to the object lubricated and normally to close the air vent and resilient means on said nipple to detachably engage'said cup thereto.

6. In a device of the class described the combination with an oil cup of a feed and filling tube extending thereinto and therefrom, means adapted to deflect the oil into the inner end of said tube, means adapted to receive the end of said tube and to be engaged to the object to be lubricated and resilient arms adapted to detachably engage the same and said cup together.

7. In a loose pulley oil cup deflector adapted to guide the oil to the discharge aperture, means adapted to connect the cup to the lubricated object and resilient means detachably engaging the same and cup together and acting against centrifugal force.

8. In a device of the class described the combination with an oil cup having a permanent bottom thereon provided with an aperture, a feed and filling tube extending through the partition to near the top of the cup, a deflector rigidly engaged to the cup adapted to supply oil to the tube, a nipple adapted to receive the end of said tube and having a passage therethrough and resilient arms carried by the nipple adapted to engage in slots in the cup to detachably engage said nipple to the cup.

9. An oil cup having a bottom provided with an air vent therethrough, a nipple. cored to permit the oil passing to the object lubricated and resilient means securing the nipple to the cupadapted to force the bottom of the cup against the nipple to prevent ingress of air through the air vent when in operation.

10. An oil cup, a nipple having a passage therethrough and resilient means detachably securing the cup to the nipple.

11. An oil cup having notches on opposite sides thereof and provided with shoulders, a nipple having a threaded lower end and a central passage to permit oil passing therethrough and oppositely disposed arms on said nipple adapted'to be sprung over the shoulders in attaching and detaching the cup to the nipple.
